KNOCKDOW'N TABLE.

Specification of Letters Patent.

Patented Aug. '7, 1906.

Application filed November 17,1905. Serial No. 287,772.

To all whom, it may concern.-

Be it known that I, J OHANNES S. WESTBY, a subject of the King of Sweden and Norway, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Knockdown Tables, of which the following is a specification.

My invention relates to knockdown tables.

' use.

In the following description reference is had to the accompanying drawings, in which Figure 1 is a plan view of my invention. Fig. 2 1s a view of the same in side elevation. Fig. 3 is a detailed plan view of one of the corners, showing one of the side rails,

partly in horizontal section, in the plane of the groove therein. Fig. 4 is a similar view showing style of latch used for locking parts together at one corner. Fig. 5 is a plan view showing two interlocking side rails with the metallic corner-piece omitted. Fig. 6 is a view of one of the side rails as seen from the inner edge, showing also the latch. Figs. 7 and 8 are detail views of the metallic corner-pieces and upper portions of the legs as seen from different sides. Fig. 9 is a view of a latch-receiving corner-piece as seen from the side shown in Fig. 8.

Like parts are identified by the same reference characters throughout the several views.

The table-top is composed of side rails 1, 2, 3, and 4, the rails 2 and 4 being hereinafter termed end rails. Each of the rails is provided with a groove 5 in its inner face, in which slats 6, which compose the central portion of the table-top, may be inserted, the slats being preferably provided with matching tongues adapted to enter the grooves in the inner faces, with the slats in the same plane as that of the side and end rails.

Each of the legs a, b, c, and d is provided with a metallic corner-piece at its upper end, which projects in theform ofa shell above theleg and is adapted to receive mortised and tenoned interlocking ends of the side and end rails. Each rail is provided with a mortise on one, end and a tenon on the other. The mortised end of the rail is inserted in the shell at the side shown in Fig. 7. A tongue 10 extends inwardly through the outer wall of the shell on this side and is adapted to en ter the mortise 11 of the rail. This tongue is provided with a lip 12, adapted to engage a shoulder 13 on the rail and within the mortised portion thereof, the shoulder 13 ex tending and abutting the tongue 10 between such lip and the outer Wall 14 of the shell, thus preventing the rail from shifting laterally. Another lip 15 extends inwardly from the inner Wall 16 of the shell and enters the groove 5 of the rail, thereby holding the lat- I ter against vertical movement, the under surface of the rail resting on the top of the leg.

The other inside face of the shell from that above described is shown in Fig. 3. This face of the shell is provided with a part 20, which extends above the top of the leg, and a tongue 21 extends inwardly from the outer wall 22 of the shell and is provided with a lip 23, which engages the shoulder 24 above the tenon 25 of the rail which is inserted on this side. The tenon 25 is provided with a notch 26 and is adapted to be manipulated-into position with the notch receiving the vertical pin 27, which crosses the mortise 11 in the interlocking rail. The positions of the-two rails when interlocked are clearly shown in Fig. 3. The under surface of the tenon 25 rests upon the upper edge of the part 20 and above the material of the rail, forming the lower wall of the mortise therein.

When the parts are interlocked, as above described, the lip 23 prevents the tenoned rail from moving inwardly, being in engagement with the shoulder 24. The pin 27 pre vents the tenoned rail from being withdrawn longitudinally, since notch 26 extends diagcpart 20. This notch is adapted to receive the latch 32, carried on one of the Tails 4, near the tenoned end, as shown by dotted lines in Fig. 4, and also shown at the left hand in Fig. 6. The tenon 33 on the rail a'is somewhat differently formed than the tenons 25 on the. other rails. The tenon 33 is not formed with a rounded margin 30, as shown on the tenon 25, but is provided with a sub-f stantially square corner filling the angle formedby the tongue in-the outer wall 14.

The tenon-33 is also formed with a longitudinallyextending notch35 for the reception of one of the pins 27 instead of the angularlyextending notch 26 of the other tenons. This construction is necessary for one corner of the table, since-in assembling the rails at the last corner the tenoned rail must be inserted in the shell in a straight line, instead of being manipulated into position by swinging it out- .wardly, as shown by dotted lines in Fig. 3.

At'this corner the latch 32 prevents-the Withdrawal of thetenon, while. at the other corners where the notch 26 is provided the tenon and pin 27 are relied upon to prevent withdrawal'.

i To assemble-the parts, the mortised end of rail 4 is inserted in the shell of-the leg 0 and the tenoned end of rail 3 manipulated into position. "The operation is then repeated to 'connect 3 and 2 withthe leg at b and the -mortised end of the rail e with the leg at a,

whereupon the slats 6 are slipped into position on theopen side and thetenoned end of 1 the rail 1 then manipulated into the shell at a and the mortised end inserted in the shell at d. "The tenon 33 on rail 4 is then inserted in the shell at d and held therein by the latch 32, which locks all the parts together, it being necessary to first release the latch before any provided with grooves in their inner edges,

adapted to receive the central-portion of the top; a pin extending across the mortise in each rail, and adapted to enter a notchin the tenon'of the interlocking rail, and a=latch on "one of the rails, adapted to engage a shellon one of the legs when the parts are assembled. J 2. In a table, the combination with a table-leg, of a metallic shell connected therewith and extending above the leg on the outer sides, said shell having tongues extending inwardly at right angles to each other and provided with lips adapted to interlock with portions ofthe table-top.

3. I11 a table, the combination with a table-leg, of a metallic shell connected therewith and extended above the leg on the outer sides, and to a less distance on one inner side: said shell having a tongue extending inwardly from the outer wall on a linewiththe top of-such wall and substantially parallel to the raised inner side -wall,and another tongue extending inwardly, substantially at right angles thereto; said tongues being provided with lips adapted to interlock with portions of the table-top.

4. In a table, the combination with a table-leg, of a metallic shell connected therewith and extended above the leg on the outer sides; a mortised rail entering said shell on one inner side, and a tenoned rail entering the shell on the other inner side, and fitting the mortised rail; a pin in the mortised rail crossing the mortise and fitting the notch in the tenon of the other rail; and tongues on said shell adapted to interlock with-said rails.

5. In a table, the combination with a table-leg, of a shell secured thereto and-provided with parts extending above the leg and adapted to interlock with the side rails, a mortised side rail adapted to enter the shell; and a tenoned side rail, adapted, when out of normal position, to enter theshell and mortise of the other rail in a'position to permit it to swing to an interlocking normal position.

6. In atable, the combination of a set of legs, each provided with upwardly-extending metallic shells; a set of marginal rails each provided atone end with a mortise, crossed by an interlocking pin, and at the other end with a notch adapted to receive a similarpin on another rail; some of the said notches being angularly formed but adapted topermit the rail to be inserted and swung into position within a shell, and one of the rails being provided with a straight notch, and a latch adapted to interlock with its respective shell.

In testimony whereof I aifix my signature in the presence of two witnesses.
